Do you do any scripts beyond extremely simple ones?

I do a fuck ton of scripting in both bash and python. I never want to do string manipulation in bash. As soon as string manipulation is required, I automatically choose python for a script. Also, if I need named arguments or multiple levels of arguments for subcommands. You can use sys.argv for basic args, which isn't any harder than bash arguments, but for complex inputs, argparse is a godsend. It has a bit of a learning curve, but it can handle anything. Bash requires you to write complex arg handling manually with loops and reducing.
